get_currentuserinfo();

echo('Username: ' . $userdata->user_login . "\n");
echo('User level: ' . $userdata->user_level . "\n");
echo('User ID: ' . $userdata->ID . "\n");
?>

get_currentuserinfo();

echo('Username: ' . $userdata->user_login . "\n");
echo('User level: ' . $userdata->user_level . "\n");
echo('User ID: ' . $userdata->ID . "\n");
?>

Using Separate Globals

Much of the user data is placed in separate global variables, which can be accessed directly.

大多数用户的数据都放置在分开的全局变数中，你可以直接访问这些变数。

get_currentuserinfo();

echo($display_name . "'s email address is: " . $user_email);
?>

get_currentuserinfo();

echo($display_name . "'s email address is: " . $user_email);
?>
